This is a pretty impressive article in terms of the amount of knowledge you've exressed of chemistry, which is all good, thanks for posting.

But without the context of the supporting system framework within which it all has to operate, there is no possibility of confirming whether or not the scheme is truly carbon neutral.

A much easier way of looking at it is from the point of view of solar energy, which has to be the source of all things, otherwise we are subtracting from the Joules incorporated in Earth, therefore practicing further damage by continuous removal of Joules incorporated in Earth.

So, as Joules are to be produced by this system, to be put to use by us, to drive us around in our cars, as well as anything else we might use it for, then the only way it can be viable, in terms of survivability of life, is for all of those Joules to come from solar.

Otherwise we are continuing to drain the Joules of energy incorporated in Earth by nature.

In other words, by not using solar, we have to be destroying Joules of Earth by default.

Carbon neutrality is something of a red-herring, when we realise the far greater significance of Joules simply destroyed by the various ways we extract energy.

Energy extracted from Earth always has to result in a net reduction of Joules put to use by nature, so that is the thing we need to stop doing. This is more fundamental than measuring how much carbon we produce. The pollution produced is an outcome of the destruction being done. The thing to worry about is the destruction of nature causing the pollution, which is far more damaging than the damage that pollution does.

So you need to be able to identify the clear solar input to your system, to show that it truly is sustainable.

Many people have done this to show how it works with hydrogen, but I am guessing not many, if any have done it to show your system working from solar, so that we might compare it with other systems known to work with solar as an input, like hydrogen.

I was looking for the part when you would explain why hydrogen was so bad, in your view, but didn't find it in your article.

So we don't really get to compare your system with hydrogen, the use of which removes batteries by fuel cell technology, so the initial problem of shortages of materials for batteries is not a concern in a hydrogen economy.
